[0003] An example construction site radio device is provided which
has at least one arithmetic unit, a radio device and a charging
device, which is provided for the purpose of inductively charging a
hand tool battery. The construction site radio device preferably
has at least one radio housing which is protected against
environmental influences at least according to protection class IP
53. An "arithmetic unit" is understood to be, in particular, a
controller having a processor, a memory unit and/or an operating,
control and/or computing program stored in the memory unit. The
arithmetic unit is preferably designed as a microcontroller. In
particular, a "radio device" is understood to be a device which is
provided for the purpose of receiving at least one radio station
and outputting the received radio station to a listener at least
acoustically. "Provided" is understood to mean, in particular,
specially programmed, configured and/or equipped. A "charging
device" is understood to be, in particular, a device which is
provided for the purpose of transmitting charging energy to a hand
tool battery during a charging operation. A "hand tool battery" is
understood to be, in particular, a battery which is provided for
the purpose of supplying a hand tool with power, in particular
during an intended use. The hand tool battery is preferably
detachably connected to the hand tool in an operational state, in
particular without a tool. Alternatively or additionally, a hand
tool battery may be integrated into the hand tool. In particular, a
"hand tool" is understood to be a portable tool, including for
example, a power drill, a combi drill, a percussion drill, a saw, a
plane, a screwdriver, a mortiser, a grinder, an angle grinder, a
gardening tool, a construction site measuring device and/or a
multifunction tool. The phrase, "inductively charge" is understood
to mean, in particular, that the charging device transmits the
charging energy to the hand tool battery via an electrical
insulator with the aid of a magnetic field. The charging device
preferably has a charging coil which transmits the charging energy
to a charging coil of the hand tool battery during a charging
operation. Due to the design of the construction site radio device
according to the present invention, it is possible to transmit the
charging energy to the hand tool battery in a manner which is
particularly insensitive to environmental influences. In
particular, the charging device does not have any sensitive, bare
contact surfaces for contacting the hand tool battery.
[0004] In another embodiment, it is proposed that the radio device
has at least one speaker, the arithmetic unit being provided for
the purpose of outputting a signal which is dependent on a charge
state of the hand tool battery via the speaker, whereby the
operator may be advantageously informed of the charge state with a
minimum amount of structural complexity. A "speaker" is understood
to be, in particular, a means which is provided for the purpose of
converting an electrical signal into an acoustic signal, in
particular in an audible frequency range. In particular, a "charge
state of the hand tool battery" is understood to be a parameter
which is dependent on an amount of energy stored in the hand tool
battery. "Dependent on a charge state of the hand tool battery" is
understood to mean, in particular, that the signal is assigned to a
charge state of the hand tool. The phrase "output a signal" is
understood to mean, in particular, that the arithmetic unit
generates, with the aid of the speaker, a sound which signals a
charge state to the operator in at least one operating state. The
arithmetic unit preferably signals at least an end of the charging
operation to the operator with the aid of the speaker. The
arithmetic unit advantageously outputs, via the speaker, a signal
which is dependent on a positioning of the hand tool battery
relative to the charging coil of the charging device.
[0005] It is furthermore provided that the example construction
site radio device has at least one display, the arithmetic unit
being provided for the purpose of outputting a piece of information
which is dependent on a charge state of the hand tool battery via
the display, whereby an advantageous representation of the charge
state may be achieved. In particular, a "display" is understood to
be a means which is provided for the purpose of visually outputting
a piece of information to the operator. The display is preferably
designed as an illuminant, particularly advantageously as a
display. The phrase "output a piece of information via the display"
is understood to mean, in particular, that the display outputs a
visual signal to the operator in at least one operating state, the
visual signal being assigned to the information which is dependent
on the charge state.
[0006] It is furthermore proposed that the arithmetic unit is
provided for the purpose of outputting at least one piece of radio
information via the display, whereby it is possible to display the
charge state and the radio information to the operator, in
particular on a single display, with a minimum amount of structural
complexity. A "piece of radio information" is understood to be a
piece of information about a radio reception which appears
meaningful to those skilled in the art, however, advantageously a
frequency of a radio station, a name of a radio station, a volume
and/or a piece of RDS information. In particular, the arithmetic
unit is provided for the purpose of outputting the information
which is dependent on the charge state of the hand tool battery and
the radio information via at least one identical display means.
[0007] It is also proposed that the construction site radio device
includes an operating element, the arithmetic unit being provided
for the purpose of at least controlling a charge state as a
function of a parameter of the operating element, whereby charging
as needed is advantageously made possible depending on the
situation. For example, hand tool batteries may be charged in a
settable sequence. In particular, an "operating element" is
understood to be a means which is provided for the purpose of
accepting an operator input from an operator. For example, the
operating element may be designed as a switch, as a button, as a
slider, as a knob, as a touch screen and/or as another operating
element. A "parameter of the operating element" is understood to
be, in particular, a state of the operating element which is
dependent on the operator input, in particular an electrically
retrievable state thereof. In particular, "at least control" is
understood to mean control and/or regulate.
[0008] It is furthermore proposed that the arithmetic unit is
provided to output at least one radio station as a function of a
parameter of the operating element, whereby the charging operation
and the radio station may be configured for the operator, in
particular with the aid of a single operating element or just a few
operating element, with a minimum amount of structural complexity.
In particular, the radio device and the charging device are
settable by the operator with the aid of the same operating
element.
[0009] In one advantageous embodiment of the present invention, it
is provided that the charging device has a charging plane and at
least one charging coil which is provided for the purpose of
charging a hand tool battery placed on the charging plane, thereby
making it possible to dispense with a fastener. A "charging plane"
is understood to be, in particular, a surface of a housing of at
least the charging device which is provided with an at least
largely flat design in an area of a charging coil. In particular, a
"charging coil" is understood to be a coil which receives and/or
transmits energy during a charging operation. The charging coil of
the charging device preferably transmits energy which charges a
hand tool battery during a charging operation. In particular, a
charging coil of the hand tool battery receives the energy. The
charging coil preferably includes at least one coil winding and, in
particular, a coil core. Alternatively or additionally, the
charging coil could be designed as an air coil. The charging coil
is preferably designed as a printed conductor on a circuit board or
particularly preferably as a wound coil. Most preferably, the
charging device is provided for the purpose of charging at least
one non-fastened hand tool battery.
[0010] In another embodiment, it is proposed that the charging
plane has at least one coil marking, which makes it possible to
comfortably position the hand tool battery for the charging
operation. A "coil marking" is understood to be, in particular, a
marking which indicates a position of the charging coil of the
charging device to an operator. The coil marking preferably
indicates to the user where he is to place the hand tool battery
for a charging operation.
[0011] It is furthermore proposed that the charging device has a
fastener and at least one charging coil which is provided for the
purpose of charging a hand tool battery fastened by the fastener,
whereby a positioning of the hand tool battery is advantageously
maintained during a movement and/or during a transport of the
construction site radio device. A "fastener" is understood to be,
in particular, a means which is provided for the purpose of
fastening the hand tool battery in a force-fit manner and/or
advantageously in a form-locked manner during a charging
operation.
[0012] It is furthermore proposed that the radio device and the
charging device are designed to be separated by an operator,
whereby a particularly flexible use is made possible. In
particular, the phrase "designed to be separated by an operator" is
understood to mean that the radio device and the charging device
have a coupling element which is designed to be detached by an
operator and which fastens the radio device and the charging device
at least to each other in at least one operating state. The radio
device and the charging device are preferably designed to be
separated by an operator without tools. Alternatively, the radio
device and the charging device may be inseparable by an operator
and/or be separable only with a loss of function of the radio
device and/or the charging device.
